QT Quick Arduino Bluetooth Help

hey guys i need alot of help i cant seem to wrap my brain around this i am very new to qt quick application but i got an interface design for my project but i am having trouble figuring out how to interface my program with bluetooth i am having trouble finding some simple examples of transmitting data from my qt quick application to my arduino.

My project:
I am building a automated mobile bar. i plan to send a string of data say for example the name of a drink from the QT Quick program over bluetooth to the arduino. the arduino will then take that string and run certain motors based on the input. i already have the arduino program running and controlling certain motors based on a string input through the serial monitor. and i already have the desired layout with my qt quick program. but i cant seem to figure out a way for my qt quick program to send a string based on a drink selected over bluetooth to my arduino.

//Buttron pins
const int button1Pin = 23; // the number of the pushbutton pin
const int button2Pin = 25; // the number of the pushbutton pin
const int button3Pin = 27; // the number of the pushbutton pin
const int button4Pin = 29; // the number of the pushbutton pin
const int button5Pin = 31; // the number of the pushbutton pin
const int button6Pin = 33; // the number of the pushbutton pin

Serial.begin(9600);
Serial.println("DRINKING COMMENCE");
inputString.reserve(200);
savedDrink.reserve(200);
}
void serialEvent() {
while (Serial.available()) {
// get the new byte:
char inChar = (char)Serial.read();
// add it to the inputString:
inputString += inChar;
// if the incoming character is a newline, set a flag
// so the main loop can do something about it:
if (inChar == '\n') {
stringComplete = true;
}
}
}
void buttonState(){

as you see in my code my if statement under my motorControl function will run certain motor based on a serial string input

The idea seems basic to me just simply call the mac address of the bluetooth module transmit the string but i know the coding is more complicated then that

can someone please help me Thank you

PS. Moderators i posted this where is best see fit but i wasn't sure so if there is a better place for this to be post it would be much appreciated if this topic was pushed to the most helpful location Thank you

oh and i also want to have show in the status bar connected but i'm sure if i could figure out the basics of using bluetooth i hopefully might be able to figure out how to say if the device is connected

do you think you can link me an example of that so i can see what your talking about i am new to qt programming and i dont know how to install a module add-on for windows and i cant seem to find out how
